Abstract
A communication terminal apparatus (130) includes a receiving unit (132) that receives distribution data distributed through a unidirectional communication network (210), an OS/application unit (131) that accepts transmission data to a tunneling apparatus (120), and a communication processing unit (133) that transmits the transmission data to a bidirectional communication network (220). When the communication processing unit (133) detects an error message of an encapsulated packet from the network (220) using a detecting unit (134), a setting unit (135) sets new transmission data that includes the error message. An error processing unit (136) subjects the transmission data to a process of resolving the error and thereafter, the transmission data is again transmitted to the network (220) to use the transmission data as distribution data from the tunneling apparatus (120).
